Hole in hydraulic oil pan

[tolgademir]

I have a small hole in the hydraulic oil pan in my Bx22. What should I pay attention to while making covering the hole with some 1/8 sheet metal. Is the hydraulic oil combustible? Do I need to drain the fluid? Thx for your help.

Hi. Welcome.

I would think the oil is combustible--it is oil.

I'm not familiar with how easy it is to remove the pan, but I think that would be the preferred method to patch it.

How'd it happen?

I think I hit a rock, sad thing is that I have the skid plate sitting in my garage waiting to be installed. The hold is near the transmission fluid drain bolt. I think there is no oil pan that can come out the transmission case is one big part. That is the reason why I need to weld in place.

Hi Tolga,

I was racing dirt/motocross bike in my young days....I did get a good repair on my transmission cassing, with an epoxy. It lasted all the years that I had it. It may be the easiest way to go. Once you get that done, take another 5 minutes to put the skid plate on..

Hope this helps,

JB weld is good stuff too. I used it once to fix a hole in a friends engine block once(water jacket). Worked great. It is a 2 part adhesive.

I second JB Weld for this repair. Drain all fluid, get hole area dry, clean with brakleen (spray brake parts cleaner), let dry (will take about 1 minute), apply JB Weld per instructions. We used JB Weld to repair electric equipment oil leaks temporarily until they could be welded. Temporary has meant up to 20 years so far. Worst case it doesn't work and you have to figure out how to weld it without burning your HST.

One problem you may run into is that the fluid will continue to seep out of the hole while you are trying to apply the JB weld. One way to stop it is to use a small fishing sinker (lead) and tap some lead into the hole first to seal it, then apply the JB weld. Tap gently with a ball peen hammer, don't make the crack worse.

I did that on a Brother-in-Law's auto transmission once and it got us home from about 300 miles away.

Don't even think about welding it in place.
JB weld is about your only alternative without removal of the pan.

If you find my thread I started last year titled "Costly Weekend" ( I don't know how to post the link??) you see my experience with the same problem. I drove a stake thru the pan and had good size gap. I drained the oil, tried to dry it up and used JB weld. No luck, to big of an opening and the pressure pushed thru. Someone told me about "MUGGY WELD". Fixed it up in a second and worked well until 2 weeks ago when a rock poked thru the center again causing a small pencil tip size hole (I have no luck) but being under pressure the oil was a flowing. Drain the oil for at least a day, rough area up with sand paper and use brake parts cleaner over and over again drying with an air hose. Mix up your JB weld and air dry with an air hose immediately, slap the stuff on nice and thick with tappered edges and let it set for at least 24 hours. Fixed it good it did, it did /forums/images/graemlins/cool.gif Good Luck...
